While I respect your initiative in trying to clean up this important resource, if you look at the front page of Classic-Castle, you'll see that the link to "Troy's Surplus Lego" is prominently featured. The reason for this is, if I remember correctly, it's the profits from his store that go towards paying for both Classic-Castle and Forbidden Cove. As a courtesy, you might want to untag this for removal.

Handar is right. Troy owns the server that CC is located on. Please do not remove his bricklink store and I would kindly request it get the top spot on that list. He ever so nicely pays for this year after year. He is also the Ambassador for bricklink.

We suggest that you contact an admin before "taking over" an existing project on Classic-Castle.

A better project would be to put out a call for all currently active Classic-Castle members with BrickLink stores to post in the thread. You could also look up the usernames of the stores in question and see the last time they posted on Classic-Castle. Then you could contact the admins to discuss updating the list.
